Data transfer service

ABSTRACT

In various embodiments, methods and systems for transferring data using a storage medium are provided. A storage medium may be shipped by a customer to a datacenter such that the data on the storage medium is copied to a storage associated with the datacenter or data in the storage is copied to the storage medium. The datacenter may support a cloud computing infrastructure that provides a storage account to the customer that is associated with the data copied from or copied to the storage medium. The storage medium further corresponds to a data transfer manifest that includes at least in part data mapping between storage service infrastructure and data in the storage medium. It is contemplated that embodiments of the present invention may further be implemented with data transfer service components that support a client component, storage service component, and a data transfer management component.

BACKGROUND

Transferring data between computing infrastructures can facilitate different types of on premise projects including the replacement and upgrade of storage, data consolidation, server maintenance, and datacenter relocation. Network-based data transfer, such as over the internet, may present certain restrictions and limitations to data transfer. Available bandwidth, customer link to the internet, and the speed to upload and download data over the internet can be limiting factors. Internet service providers may also retain control of network traffic making data transfer expensive and/or slow. Physically moving storage media, in order to transfer data, may help improve a data transfer project in situations where uploading over the Internet is prohibitively expensive, time consuming, or not feasible due to the available bandwidth. However, conventional methods for circumventing network-based data transfer fail to provide integrated management, security, data mapping, and data validation in data transfer services.

SUMMARY

This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used in isolation as an aid in determining the scope of the claimed subject matter.

Embodiments of the present invention provide a method for transferring data using storage media. This may be accomplished by receiving a storage medium at a storage service infrastructure. In particular, in one example, the storage medium may be a hard drive shipped by a customer and received at a datacenter, such that, the data on the hard drive is copied to storage associated with the datacenter. Other types of storage media are contemplated with embodiments of the present invention. The datacenter can include a storage service infrastructure that is part of a distributed cloud computing infrastructure. The distributed cloud computing infrastructure can provide a storage account to the customer that shipped the storage medium. A data transfer manifest may be associated with data transfer objects that facilitate data transfer operations for storage medium. The data transfer manifest, in particular, provides data mapping for data identified for data transfer operations. The storage medium corresponds to a data transfer manifest. The data transfer manifest may optionally be stored in the storage medium. The data transfer manifest can also be communicated electronically to the storage service infrastructure. In embodiments, additional data transfer objects are communicated separately to the storage service infrastructure. The data transfer manifest may be stored in the storage medium using a data transfer client component during an import job. The data on the storage medium may then be copied, based on the data transfer manifest, to storage associated with the datacenter. The storage account may provide access to the data copied to the storage.

Additionally, a data transfer manifest may be generated using a data transfer storage service component during an export job. The export job comprises a storage medium that corresponds with a data transfer manifest, the storage medium is shipped to the customer, such that, data copied from a storage account in the distributed cloud computing infrastructure to the storage medium. The customer may then copy the data in the storage medium to the customer infrastructure.

It is contemplated that the data transfer service supports a data transfer service infrastructure having the data transfer client component and the data transfer storage service component, that provide for data security, data mapping, and data validation, and a data transfer management component that is configured for tracking, generating tasks, and providing logical states for data transfer jobs.

DETAILED DESCRIPTION

The subject matter of embodiments of the invention is described with specificity herein to meet statutory requirements. However, the description itself is not intended to limit the scope of this patent. Rather, the inventors have contemplated that the claimed subject matter might also be embodied in other ways, to include different steps or combinations of steps similar to the ones described in this document, in conjunction with other present or future technologies. Moreover, although the terms “step” and/or “block” may be used herein to connote different elements of methods employed, the terms should not be interpreted as implying any particular order among or between various steps herein disclosed unless and except when the order of individual steps is explicitly described.

For purposes of this disclosure, the word “including” has the same broad meaning as the word “comprising.” In addition, words such as “a” and “an,” unless otherwise indicated to the contrary, include the plural as well as the singular. Thus, for example, the requirement of “a feature” is satisfied where one or more features are present. Also, the term “or” includes the conjunctive, the disjunctive and both (a or b thus includes either a or b, as well as a and b).

Transferring data between computing infrastructures can facilitate different types of on premise projects including the replacement and upgrade of storage, data consolidation, server maintenance, and datacenter relocation. Network-based data transfer, such as over the internet, may present certain restrictions and limitations to data transfer. Available bandwidth and the speed to upload and download data over the internet can be limiting factors. Internet service providers may also retain control of network traffic making data transfer expensive and/or slow. Physically moving storage media, in order to transfer data, may help improve a data transfer project in situations where uploading over the Internet is prohibitively expensive, time consuming or not feasible due to the available bandwidth. However, conventional methods circumventing network-based data transfer fail to provide integrated management, security, data mapping, and data validation in data transfer services.

Embodiments of the present invention provide a simple and efficient method for transferring data using storage media. At a high level, data transfer service components are implemented to provide data transfer services (e.g., importing and exporting of customer data) associated with a customer infrastructure (e.g., one or more customer computing devices) and a storage service infrastructure. The data transfer service can provide an interface which allows a customer to perform data transfer operations. In an exemplary embodiment the interface is a Representational State Transfer (REST) interface which allows a customer to perform data transfer operations. The data transfer service components can utilize REST Application Programming Interfaces (APIs) to enable programmatic control of the data transfer jobs. The REST interface can be implemented and/or invoked in via a web-based portal to further facilitate performing one or more of the data transfer operations for the storage service infrastructure and the customer infrastructure. Other combination and variations of interfaces are contemplated with embodiments of the present invention.

A customer infrastructure (e.g., one or more customer computing devices) may implement a data transfer client component and a storage service infrastructure may implement a data transfer storage service component to facilitate data transfer operations. A data transfer operation can include a request to an interface that connects the data transfer client component or a data transfer storage service component to the storage service such that the operation is executed to perform a data transfer job. In addition, a storage medium may be configured with a manifest to either import data from the storage medium to storage account storage of a storage service infrastructure or export data from the storage service infrastructure to storage of the customer infrastructure.

The storage service comprises several components including data transfer service components for implementing data transfer service operations. The data transfer service components include the data transfer client component, and the data transfer storage service component, and can further include a data transfer management component in a networked environment. The data transfer client component and the data transfer storage service component may each support securing the data transfer service by protecting the storage service infrastructure from malicious storage media and protecting customer data. In addition, in either an import job or export job, a data transfer client component and the data transfer storage service component may provide for verifying the data transferred in order to identify and correct errors (e.g., errors caused by physical damage to the storage medium during transport) or failures (e.g., failures during data transfer process) and then the identified errors may be corrected. Further, the data transfer management component may be configured for tracking storage media that are transported from the customer infrastructure, generating tasks based on the progress of the data transfer jobs associated with the storage media, and providing for display, internally to storage service administrators, and externally to customers, the status of the storage media during a storage service import or export job.

For purposes of a detailed discussion below, embodiments of the present invention are described with reference to a storage media and a plurality of data transfer service components in a data transfer service infrastructure; however the storage media and the data transfer service components depicted herein are merely exemplary and should not be construed as limiting. For example, the use of drive or hard drive interchangeably with storage medium is not meant to be limiting. Further, while embodiments of the present invention may generally refer to a data transfer service infrastructure and the schematics described herein, it is understood that the techniques described may be extended to other implementation contexts.

Embodiments of the present invention may be described by way of exemplary implementations in a data transfer service infrastructure that can be a portion of a storage service infrastructure. During an import job, a customer may configure a storage medium (e.g., hard drive) using a data transfer client component. The storage medium includes data which the customer would like transferred from their location (e.g., customer infrastructure) to a storage associated with a storage account in a storage service infrastructure. The data transfer client component may be used to associate a storage medium with a data transfer manifest used in facilitating data transfer operations. Data transfer operations include copying the data on the storage medium to the storage account storage. During an export job, the data transfer storage service component may be used associate a storage medium with a data transfer manifest used in facilitating data transfer operations. Data transfer operations include copying the data on the storage medium to customer infrastructure storage.

Embodiments of the present invention further utilize a data transfer manifest. The data transfer manifest (hereinafter “manifest”) generally refers to a configuration file that describes the mapping between storage service infrastructure data and data on the storage medium associated with a data transfer job. The manifest can be stored into the storage medium and/or have at least associated portions thereof communicated separately in order to perform storage services. The manifest may be communicated to the storage service infrastructure electronically and separately from the storage medium.

The manifest can be created with a plurality of different data transfer objects that facilitate performing data transfer operations. Data transfer objects refer to constant or variable parameters of the data transfer service that provide for a specific function in data transfer operations. Data transfer objects can include a location object, a data object, a security object, and a validation object that facilitate performing data transfer operations associated with each corresponding object or combination of objects.

By way of examples, in an import job, the location object (e.g., blob path and file path) may help identify the location, for example in a storage account, where the customer data should be stored, and in an export job, the location object (e.g., blob path and file path) may identify the location, for example in a storage account, from which the customer data should be retrieved. A data object associated with an import job or an export job can identify data (e.g., blob or file) that can be transferred between the storage medium and the storage service infrastructure. The security object (e.g., an encryption security object, or a key security object) can encrypt and/or authenticate the storage medium, and the validation object may be used in verifying the copied data and facilitating repair of any failures or errors. Additional data transfer objects may be communicated separately to the storage service infrastructure. For example, an alternate or complimentary security object (e.g., hash key) may not be communicated in the storage medium but communicated separately (e.g., electronically using a secure channel) to the storage service infrastructure. Any other variations and combinations of data transfer manifest data transfer objects are contemplated within embodiments of the present invention.

In embodiments of the present invention, the data transfer service components may support securing data transfer service based on securing the storage service infrastructure and protecting customer data. The data transfer client component and the data transfer storage service component may both secure the data transfer service based on a corresponding role of the components in the different storage service jobs. In this regard, it is contemplated that the components may perform similar securing tasks in securing the data transfer service depending on a corresponding role in a data transfer job as discussed in more detail below.

The data transfer client component may facilitate securing the storage medium with security objects. The data transfer client component may request a drive unique identifier (e.g., serial number of a drive) when creating an import job. The data transfer client component may also facilitate encryption and/or identification of the type of encryption (e.g., MICROSOFT WINDOWS BitLocker) used for the storage medium. The drive unique identifier and the encryption keys for the storage medium may be communicated to the storage service infrastructure. The drive unique identifier and the encryption keys can be communicated using a secure channel. The encryption keys can be used to decrypt the storage medium. It is contemplated that the encryption keys and/or the drive unique identifier can be used to perform data transfer operations including at least one of identifying, validating, and decrypting the storage medium.

Similarly, during an export job, the storage medium may also be encrypted. The data transfer storage service component can facilitate the encryption of the storage medium and identification of the type of encryption (e.g., MICROSOFT WINDOWS BitLocker) used for the storage medium. The encryption keys for the storage medium may be communicated to the customer infrastructure. The encryption keys can be communicated using a secure channel. The encryption keys can be used to decrypt the storage medium. It is further contemplated that the encryption keys and/or the drive unique identifier can be used to perform data transfer operations including at least one of identifying, validating, and decrypting the storage medium.

In an alternate embodiment, a portion of the storage medium may be hashed to support securing customer data and the storage service infrastructure. In particular, the portion may refer to a section of the storage medium that facilitates access to retrieve the data on the storage medium. The portion of the storage medium may include the master boot record with a boot sector and/or metadata that define files, back up critical system data, buffer file system changes, and free space allocation. The portion of the storage medium may also include a master file table that describes the files on the volume, including file names, time stamps, compression, encryption etc. As such, the portion of the storage medium can be a beginning portion of the storage medium. By way of example, the data transfer client may generate a hash of the portion of the storage medium, encrypt the hash, and send the encrypted hash. The encrypted hash can be sent separately from the storage medium using a secure channel. Upon receiving the storage medium at the storage service infrastructure, the storage medium may then be decrypted by the data transfer storage service component based on the encrypted hash to verify the integrity of the portion of the storage medium. When the integrity of the portion of the storage medium is verified, the storage medium can provided for data transfer processing. In particular, the storage medium may be accessed based at least in part on the verified portion of the storage medium. Other variations of hashing techniques are contemplated with embodiments of the present invention.

During an import job or an export job, a storage medium can be protected from a malicious party who may intercept the storage medium in transport from customer infrastructure to a storage service infrastructure or vice versa. In particular, the security concern may be that in transit the storage medium can be intercepted and malicious data can be stored on the storage medium. However, because the data transfer service components support an encrypted storage medium prior to shipping the storage medium, the malicious party would not know the encryption key to decrypt the storage medium and thus could not store malicious data into the encrypted region of the drive, resulting in the customer data being protected from malicious actions. In embodiments, an encryption key for the storage medium and the encrypted storage medium are not communicated together, as discussed in more detail below.

The data transfer service components may further support securing and protecting the storage service infrastructure. Upon a storage medium for an import job arriving at the storage service infrastructure, additional secure steps may be performed. The encrypted storage medium may be first attached to a virtual machine (VM) without reading the storage medium in the host operating system. The encryption key may be provided to the VM. Each VM can be segregated, based on physical or virtual security mechanisms, from the storage service infrastructure until the storage medium is verified such that additional security to the storage service and the hosting operating system. Each VM can be used for one storage medium, and the VM can be assumed to be compromised once the storage medium has been mounted. As discussed above, the VM may facilitate the process of verifying the integrity of the portion of the storage medium based on the hash encryption. The VM may further run software that should upload the data from the storage medium to the storage account, and the software can send notifications as the software makes progress copying the data into a storage account of a customer. The progress on the VM can be monitored to confirm advances in the copying process. Additional investigations may be undertaken to confirm whether a bug is impeding progress or if the VM has been compromised by a malicious drive.

The data transfer service components may further support validation and repair. At a high level, in order to validate that customer's data is correct through the transfer process, a checksum of data on storage medium may be stored. For example, an MD5 checksum of each file on a drive. For large files, files may be divided into chunks with corresponding stored checksums for each chunk. By way of example, for an import job at the customer infrastructure, checksums can be computed and stored on the storage medium as the customer is populating the storage medium with data.

At the storage service infrastructure during the import job, the checksums can be validated as the data is imported into a storage account. For example, the MD5s of each file as the file is written to the customer's storage account. It is contemplated that other types of checksum variations beyond MD5 may be implemented with embodiments of the present invention. If the checksum does not match, instead of importing the data, information can be recorded (e.g., log object) about the data that did not match into known location associated with the customer's import job. A repair operation may be executed based on the recorded information. In particular, the data transfer client component may be used to identify the missing or damaged data and upload the parts that were missing. The data uploaded via the data transfer client component may also be verified using checksum.

During an export job, checksum data, for individual files or portions of large individual files, can be stored on the storage medium using the data transfer storage service component. Upon receiving the storage medium, the customer may use the data transfer client component to validate the data on the storage medium that are transferred to the customer infrastructure. If the checksum does not match, a repair operation, according to methods of the present invention, can be implemented. A repair operation may be executed based on configuring the repair operation to automatically repair data during the checksum validation operation. Alternatively, the repair operation can be independently executed. The data transfer client component may be used to identify the missing or damaged data and download the parts that were missing from the storage service infrastructure. The data downloaded via the data transfer client component may also be verified using checksum.

Data transfer management may be facilitated by a data transfer management component. In particular, the data transfer management component may be configured to provide tracking for storage media that are transported from the customer infrastructure, generating tasks based on the progress of the data transfer job associated with the storage media, and registering and providing the registered logical states via an interface (e.g., display) internally to storage service administrators, and externally to customers, the logical states of the storage media during a storage service import or export job. For example, the storage data transfer management component may be responsible for tracking the storage medium from the time the customer configures the data on the storage medium through to a point where the storage medium is shipped back to the customer and/or processed at the customer infrastructure (e.g., a repair operation on the storage medium).

The data transfer management component may additionally support the logistics and generation of tasks associated with transporting the storage medium, receiving the storage medium, retrieving the data from the storage medium or loading data onto the storage medium, and transporting the storage medium back to the customer. In this regard, the progress of a storage medium during a data transfer job may be referenced and provided to a designated entity. In particular, storage service administrators may be provided with an internal view of the status based on the progress of the storage medium, while customers may have a client-service interface that displays an external view of the status of the data transfer job based on the progress of the storage medium during the data transfer job. As such, status information may be tailored for the different types of designated entities when informing the designated entity of the status of the storage medium.

In particular, during an import job, the data transfer client component 204 generates a manifest 218A associated with the import job for a storage medium 216A. The manifest 218A describes the mapping between data storage service infrastructure and data in the storage medium for an import job. For example, a file in a hard drive may be mapped to a blob in the storage service infrastructure 208. During an import job, the manifest 218A can be created by the data transfer client component 204 as part of the preparation of the storage medium 216A. The manifest 218A may be stored on the storage medium 216A prior to shipping the storage medium 216A to the storage service infrastructure 208.

The data transfer storage service component 210 of the storage service infrastructure 208 may function as a portion of the data transfer service facilitating data transfer operations. The data transfer service, upon processing a storage medium associated with an import job or export job, generates a log object in association with the storage account of the data transfer job. For example, when the data transfer storage service component 210 processes a storage medium associated with a data transfer job, the data transfer storage service component 210 may generate a log object that is a copy log file. In embodiments, the log object is associated with a storage account from which the data is imported to or exported from. The log object can contain details about each file that was imported and exported. The log object may be written to block blobs and associated with operations for configuring a location of the storing the log object in the storage service infrastructure and retrieving the storage a URI for the log object. A URI to each copy log file may be returned when a query of the status of the job is requested.

The log object may in particular log failures to copy data (e.g., individual files or parts of a file) to the storage service. In this regard, there may be two different types of log objects written to the storage account; they include: an error log, which is generated in the event of an error, and a verbose log that may not be enabled by default, but may be enabled by a customer action. The verbose log may contain complete information about the status of the copy operation for data (e.g., every blob (for an import job) or file (for an export job)), whereas the error log may contain only the information for data that encountered errors during the data transfer job. The object may be written to block blobs containing XML descriptions of events that occurred while copying data between the storage medium and the customer's account. Several different types of XML elements are contemplated with embodiments of the present invention. XML elements can be related to data transfer objects, for example, XML elements include Blob/FilePath associated with the location object, Hashes for all or portions of the data, Metadata, Properties, associated with authentication security object (e.g., storage account key) and Offsets and lengths for portions of the data.

The log object can identify different types of issues or error events associated with the storage medium. Error events may include errors in accessing or reading the manifest file, incorrect authentication security object (e.g., key), storage medium read/write error. Additional error events may be directed particularly to the data associated with the storage medium, for example, blobs and files. As such, by way of example, additional error events can include incorrect or conflicting blob or names, missing files, blob not found, truncated files (the files on the disk are smaller than specified in the manifest), corrupted file content (for import, detected with a checksum mismatch), corrupted blob metadata and property files (detected with checksum), incorrect schema for the blob properties and/or metadata files.

During an export job, the data transfer storage service component 210 generates a manifest 218B associated with the export job of a storage medium 216B. The manifest 218B describes the mapping between data in the storage service infrastructure and data in the storage medium 216B for an export job. For example, blobs in the storage service infrastructure 208 may be mapped to a file in a hard drive. During an export job, the manifest 218B can be created by the data transfer storage service component 210 after receiving the storage medium 216B from the customer infrastructure 202. The manifest 218B may be stored on the storage medium 216B prior to shipping the storage medium 216B back to the customer infrastructure 202.

The manifest 218A and 218B (“manifests”), which are generated at the customer infrastructure 202 and the storage service infrastructure 208 based on the storage service job, may be associated with different data transfer objects to support data transfer operations, where the operations include copying, managing, secure, and validating data. The manifest may include an enumeration of the data on the storage medium and the mapping to the storage service. For example, the manifest may enumerate the files intended for upload and the mappings from the files to blobs in the storage service. The manifest may further include information about the metadata and properties to associate with data transferred to the storage service infrastructure. The manifest may also include a list of the actions to take when data being uploaded conflicts with existing data in the storage service. The manifest may also include checksums of segments of each file. Checksums generally refer to a small-size of data computed from an arbitrary block of data for the purpose of detecting error which may have been introduced during transmission or storage.

The manifests may be written with Extensible Markup Language (XML) descriptions. Several different types of XML elements are contemplated with embodiments of the present invention. XML elements can be related to data transfer objects, for example, XML elements include blob file path, associated with the location object, storage account key associated with authentication security object, hashes for portions of file, metadata, and properties associated with a validation object.

The manifests may further be backed up. The manifests can be automatically backed up into the storage service infrastructure executing an operation to configure backing up the manifests. In this regard, it is contemplated that the manifest can be simultaneously stored on an associated storage medium and a storage service infrastructure. The backups of manifests can be stored in association with the storage account associated with the job. The name of the manifests may be a predefined name but that can be overridden by specifying a different name based on an operation at the data transfer client component. A Uniform Resource Identifier (“URI”) of the backup manifest for a data transfer job can also be retrieved via an operation at the data transfer client component. The URI can be returned as a manifest URI for each drive.

The data transfer management component 212 (“management component”) of the storage service infrastructure 208 may be configured to manage a plurality of tasks associated with data transfer operations. In particular, the management component 212 may support tracking storage media, for example, the management component 212 may support tracking for storage medium 216A and storage medium 216B that are transported between the customer infrastructure 202 and the storage service infrastructure 208. The management component 212 may further be configured for generating tasks based on the progress of the data transfer job associated with the storage media, for example, storage service administrators may be directed to receive a package, unpack the package, and move one or more storage media to a staging area, insert drives into machines, remove drives from machines, and ship drives back to customers.

Additionally, the management component 212 may be configured for registering logical states of data transfer artifacts and providing the registered logical states via an interface (e.g., display) internally to storage service administrators, and externally to customers, the status of the storage media during a storage service import or export job. In particular, the management component 212 can include a state machine module (not shown) that manages different data transfer artifacts (e.g., job, drive, drive bay, package, ticket and health) and provides logical states for each monitored data transfer artifact based on the progress of the import or export job. The logical state may be specifically based on attributes of the data transfer artifact, as discussed in more detail below.

With reference to FIG. 3A, the data transfer client component 310 provides interfaces to facilitate data transfer operations. In one embodiment, the data transfer client component 310 can include a client tool 310A and a client-service interface 310B. The data transfer client component 310 interfaces are configured to facilitate creating data transfer jobs 340. The interfaces can be implemented and/or invoked in via a web-based portal to further facilitate performing one or more of the data transfer operations for the storage service infrastructure and the customer infrastructure. The data transfer service components can utilize REST Application Programming Interfaces (APIs) to enable programmatic control of the data transfer jobs. In particular, the REST APIs may provide Hypertext Transfer Protocol Secure (“HTTPS”) endpoints for communicating between the customer infrastructure and the storage service infrastructure. The data transfer client component may access the storage service via the client-service interface 310B (e.g., web-based management portal 310C). Access to the storage service through the client-service interface 310B can be secured by providing access using mutual authentication management certificates to ensure that a request made to the storage service is secured. It is contemplated that an implementation of the REST APIs can be the client-service interface 310B as a web-based management portal or a client-service interface 310B as a programmed interface (not shown) to access the storage service.

With reference to FIG. 3B, the data transfer client component 310 may support performing data transfer operations. Data transfer operations can include preparing storage media for data transfer jobs 320, creating data transfer jobs 340, reviewing job status 360 based on data transfer objects, and repairing data transfer jobs based on a log object 380. The data transfer client component 310 may, in one embodiment, be an executable file installed at the customer infrastructure (e.g., a customer computing device) from which the data transfer client component is executed and used to facilitate storage services in accordance with embodiments of the present invention. Preparing a storage medium may include satisfying one or more prerequisites. It is contemplated that one or more of the prerequisites are not mandatory but preferred in order to prepare the storage medium for a data transfer job. Prerequisites may include a subscription to a storage service of the storage service infrastructure, a storage account associated with the subscription, an account key for the storage account, and an encrypted storage medium.

The data transfer client component 310 can create data transfer jobs. Creating data transfer jobs can include customer actions and data service component operations that may be similar and/or overlapping to achieve data transfer goals, as described in more detail below. The data transfer client component 310 may be configured to create an import job and an export job. The import job may be created using the client tool 310A and client-service interface 310B. Creating the import job can include preparing the storage medium 320 with the client tool 310A. Preparing the storage medium for an import job may include several different import job preparation operations 320A performed at the data transfer client component 310. The import job preparation operations may comprise receiving a selection of data to be imported to a storage service infrastructure, receiving a selection of a destination location for the data, copying the data to the storage medium, and generating an import manifest for the storage medium. The manifest can be stored on the storage medium such that the data on the storage medium is copied from the storage medium by referencing the manifest. The manifest can also alternatively or in addition be communicated to the storage service electronically (e.g., internet).

Preparing a storage medium for an import job comprises actions associated with the import job preparation operations. The actions may include identifying the data to import into the storage service infrastructure, identifying the target location for the data, determining the number of storage media needed, and copying the data to each of the storage media. The storage service infrastructure may support blob storage and/or file storage, such that, data is transferred into blobs and/or files.

Identifying the data to be imported into the storage service infrastructure may include determining which directories and files are imported to the storage service infrastructure. This can be a list of directories, a list of unique files, or combination thereof. When a directory is included, all files in the directory and the subdirectories can be part of the import job. Identifying the target location for the data can include identifying the destination locations in blob service of the storage service infrastructure. In particular, for each directory of a file that may be imported, a destination virtual directory or blob in the storage service infrastructure may be identified. For example a source file a directory can be: H:\Video and a destination blob or virtual directory can be: https://mystorage account.blob.net/video

Copying the data to the storage media comprises copying the data to the storage media based on copy sessions. A copy session may be created for each storage medium to which the data is copied. It is contemplated that more than one session may be needed to copy all the data to a single storage medium because a copy session may copy either a single directory or a single blob to a storage medium. If multiple directories or multiples blobs are copied then multiple sessions may be needed. In addition, if specific properties and metadata are associated with blobs imported as part of the import job, the specific properties and metadata associated with blobs are specified by copy session. In order to provide different properties or metadata for additional blobs, a separate copy session may be needed. To set blob properties, a text file can be created on the computing device running the data transfer client component. To set blob metadata, a text file can be created that specifies metadata names and values. A path to one or both of the blob properties or blob metadata may be passed to the data transfer storage service component to associate the blobs with the properties and metadata. It is contemplated that multiple computing devices may run a data transfer client component in parallel in order to copy data to multiple storage media.

The data transfer client component 310 may further create a journal file for each storage medium. The journal file for each storage medium may be needed to create an import job. The journal file may further be used to resume preparation of the storage medium if the data transfer client component is interrupted. A command line interface may be used to facilitate specifying the journal file in order to resume running the data transfer client component. Using the command line interface or any other appropriate interface, copying the data to the storage media may specify several data transfer objects associated with the import job. The command line may include, amongst others, location objects (e.g., source directory and destination directory) authentication security object (e.g., storage account key), an encryption security object (e.g., disk encryption) and a journal file object as parameters associated with the copied data. For example, the storage account key can be the account key for the storage account to which the data will be imported, the disk encryption may encrypt drive when the drive is not already encrypted or when the drive is already encrypted, the disk encryption may specify the key of the drive. Several data transfer objects are contemplated with embodiments of the present invention including source directory, destination directory, session identification, a disposition in case of a conflict, blob type, property file and metadata file.

Additionally, to prepare the storage media for an import job, the command line interface may include data transfer objects that depend on whether the copy session is the first copy session, or a subsequent copy session. By way of example, the first copy session for a drive can have some additional objects to specify the storage account key; the target drive letter; whether the drive must be formatted; whether the drive must be encrypted and if so, the encryption key; and the log directory. As such, the data transfer client may implement a syntax for configuring the objects.

The client tool 310A is further configured to generate a manifest for each storage medium as the storage medium is prepared. As discussed above, the manifest can include an enumeration of the data intended for upload and the mapping between storage service infrastructure and data on the storage medium, checksums of segments of the data, information about the metadata and properties to associate with each the data copied to the storage service infrastructure, and listings of actions to take if data being uploaded have conflicts.

Creating an export job can include preparing for the export job 320B with the client tool 310A. Preparing for an export job may include several different export job preparation operations 320B. The export job preparation operations may comprise identifying a selection of the data to export from the storage service infrastructure, and determining the number of storage media needed. The storage service infrastructure stores the data (e.g., blobs and/or files), such that, data is transferred from storage service infrastructure into the storage medium. In one embodiment, blobs stored in the storage service infrastructure may be converted into individual files that are transferred to the storage medium. The storage service infrastructure may further store snapshot data to be transferred. A snapshot data may refer to a version of the data (e.g., blobs and/or file) captured at a particular time. Snapshot data may be associated with a snapshot object in the data transfer manifest. Snapshot data may have been identified by a user as important when the data was in that version or may have been automatically created by the storage service infrastructure based on one or more policies. In this regard, active data may exist simultaneously with corresponding snapshot data in the storage such that at least portions of either or both may be identified (e.g., via a snapshot object) for an export job. Further, preparing a storage medium for an export job comprises actions associated with the export job preparation operations. The actions may include identifying the data to be exported, and providing the number of storage media needed. It is contemplated that the export job preparation operations and actions may optionally include the storage service identifying a target location for the data based on a user provided target location for the data,

Identifying the data may comprise selecting the data in the storage service infrastructure to be copied to the storage medium. In particular, one or more of a relative blob path to select a single blob or snapshot, a blob prefix to select all blobs or snapshots of the given prefix, and all blobs or snapshots in the storage account can be selected to be transferred to the storage medium. Similarly the relative paths to files or snapshots thereof may be identified for transfer.

The client tool 310A is further configured to help the customer identify the number of storage media needed to export the data based on the total size of the data selected to be exported. In one embodiment, a total size of the data to be exported may be calculated. A list of the data to be exported may be generated and the sum of the sizes of the data can be calculated for each data item (e.g., blob) to be exported. The calculation can take into account the size of the storage media, the sizes of data transfer objects and additional overhead of the storage media. For example the manifest size and the disk sector error rate. A summary of the data to be exported may be provided. Based on the total data size, the total number of storage media may be determined.

With continued reference to FIGS. 3A-B, the data transfer client component 310 may further facilitate creating data transfer jobs 340. Creating an import job may be associated with a create import job operation 340A at the client-service interface 310B. In addition several actions may be associated with the create import job operation 340A. For example, infrastructure information (e.g., datacenter location, name and address) to which the storage medium is shipped may be identified. The storage service infrastructure information may be identified from a list of locations, where at least one location supports a storage account of the customer having the storage medium. The storage service infrastructure information may be identified via the client-service interface 310B based on retrieving a list of locations and selecting a location from the returned list of locations.

The client-service interface 310B may support an operation to create an import job. The client-service interface 310B may issue the operation to the storage service. The operation may include several different parameters that facilitate performing data transfer operations. Parameters may be associated with a location object, a security object, or a validation object. By way of example, parameters may include name for the job, storage account name, storage account key, storage service infrastructure information, data transfer job type, return address, list of storage media. Each storage medium may further be associated with parameters including a drive identification, an encryption key, a location of the manifest on the storage medium, and a checksum hash. A customer can the ship the storage medium based on the storage service infrastructure information. The customer receives package information for the storage medium. The client-service interface may update the data transfer job with the package information. The package information may include the carrier and the tracking number for the storage medium shipment.

Creating an export job may be associated with a create export job operation 360B at the client-service interface 310B. In addition, several actions may be associated with the create export job operation 340B. For example, infrastructure information (e.g., datacenter location, name and address) to which the storage medium is shipped may be identified. The storage service infrastructure information may be identified from a list of locations, where at least one location supports a storage account of the customer having the storage medium. The storage service infrastructure information may be identified via the client-service interface 310B based on retrieving a list of locations and selecting a location from the returned list of locations.

The client-service interface 310B may issue an operation to the storage service to create the export job. The operation may include several different data transfer objects as parameters that facilitate performing data transfer operations. Parameters may be associated with a location object, a security object, or a validation object. By way of example, parameters may include name for the job, storage account name, storage account key, storage service infrastructure information, data transfer job type, return address, list of storage media. A customer can then ship the storage medium based on the storage service infrastructure information. The customer receives package information for the storage medium. The client-service interface may update the data transfer job with the package information. The package information may include the carrier and the tracking number for the storage medium shipment.

After the export job has been processed at the storage service infrastructure, the storage media will be returned with encrypted data. The customer may retrieve an encryption security object (e.g., MICROSOFT WINDOWS BitLocker key) for each storage medium by calling an operation at the client-service interface. The customer can unlock the storage media encryption using the encryption security object. The storage media contains the manifest on each storage medium. The manifest contains a listing of data on the storage media as well as the original locations in the storage service infrastructure. For example, the manifest can include a list of files on a hard drives and the original blob address for each file in the storage service infrastructure.

With continued reference to FIG. 3, the data transfer client component 310 is configured to facilitate review of the job status 360 with based on log objects. During an import job or export job copying the data to or from the storage medium can be associated log objects. The log object contains detailed status about each file that was imported or exported. The URL to each copy log file can be returned when you query the status of a completed job. For example, a status of data copied may refer to the state or condition of the data (e.g., file) during a copy session. The status associated with data may be designated by different status codes. Several different types of status codes may be used, with a least a portion of the status codes associated with XML elements and data transfer objects.

With continued reference to FIG. 3, the client tool 310A may further be configured to repair a data transfer job 380. Failures may be caused by file corruption, damaged storage media, or change in storage account key. Based on import repair operations, the client tool 310A may use a log object associated with the storage medium to upload missing files (or part of a file) to the storage service infrastructure or download missing files (or part of a file) to the customer infrastructure. In this regard, the repair import is completed based on streaming data over the network. In operation, the log object is passed to the client tool 310A such that the tool completes the import for the file by copying the missing contents across the network. By way of example, the client tool 310A may look for the original file within the corresponding directories in the customer infrastructure and copy the missing range of data to the corresponding blob and/or file in the storage service infrastructure. It is contemplated that the customer may identify corresponding directories in any location to copy the missing range of data to the corresponding blob and/or file in the storage service infrastructure. A command for repairing an import job may include a data transfer objects as parameters, the parameters including a repair file, a log directory, a target directory, an encryption-based security object, a key-based security object, a storage account name, a log object, and a path map file object. In particular, the repair file can track the progress of the repair, and the repair file may be used to resume an interrupted repair. Each drive may be configured with one repair file. When a repair is started for a storage medium, a path of the repair file, which does not yet exist, is passed.

The client tool 310A may also be used to resolve conflicts between two files. In some occasions, the client tool 310A may not be able to find or open a necessary file, either because the file is not found, the file name is ambiguous, or the content of the file is no longer correct. For example, an ambiguous error could occur if the client tool 310A is trying to locate a first file based on a relative path and there is a file with that same name under multiple directories. The path map file object may be used to resolve such an error in that the path may file may specify a name of a path map file that does not exist and the client tool 310A can populate a list of files which the client tool 310A is not able to correctly locate.

With reference to export repair operations 380B, repairing an export job may comprise downloading any data that the storage service infrastructure may have been unable to export, and validating the data on the storage medium was correctly exported. The data transfer client component needs connectivity to the storage service infrastructure to support the repair functionality. The client tool 310A may use a log object associated with the storage medium to download missing files (or part of a file) from the data storage service. In this regard, the repair export is completed based on streaming data over the network. In operation, the log object is passed to the client tool 310A such that the tool completes the export for the file by copying the missing contents across the network. By way of example, the client tool 310A may look for the original file within the corresponding directories in the storage service infrastructure and copy the missing range of data to the customer infrastructure. A command for repairing an export job may include data transfer objects as parameters, the parameters including a repair file, a log directory, a target directory, an encryption-based security object, a key-based security object, a storage account name. In particular, the manifest of the export job, generated by the storage service and stored on the storage medium and optionally in the storage account, may be used to for data validation based on security objects in the manifest. In this regard, any files that are determined to be corrupted can be downloaded and rewritten to the target directories.

In operation, the storage medium containing the exported files may be connected to the customer infrastructure. The client tool 310 may be pointed to the storage medium and a location of the log object. The log object may be downloaded from the storage service infrastructure. The log object contains a list of files that failed to export. In particular, the log object may indicate that a failure occurred while the storage service was downloading the data (e.g., blobs to files) to store in the storage medium. Other components may have been downloaded successfully. As such, client tool 310A may download failed data from the storage service infrastructure and write it to the customer infrastructure. It is further completed that a repair may be performed based receiving an additional storage medium with data used to repair either an import job or export job in accordance with embodiments of the present invention.

With continued reference to FIG. 2, the data transfer management component 212 (“management component”) may be configured to provide tracking for storage media that are transported from the customer infrastructure, generating tasks based on the progress of the data transfer job associated with the storage media, and providing for display, internally to storage service administrators, and externally to customers, the status of the storage media during a storage service import or export job. In particular, the management component 212 may include a state machine 220 for facilitating the performance of data transfer operations associated with the management component. The state machine 220 may be a component or module as defined hereinabove. The state machine 220 can support monitoring several different data transfer artifacts associated with logical states. A specific state machine can manage logical states that refer to a construct that alters during a data transfer job with reference to data transfer artifacts, such that, logical states based on retrieved information can be associated with the data transfer artifacts by the state machine as the data transfer job progresses. State machines can include the job state machine, drive state machine, the drive bay state machine, the package state machine, a ticket state machine, and an entity health state machine each associated with corresponding data transfer artifacts. The state machine 220 is configured for managing the progress of a data transfer job and further detecting errors and failures, and facilitating recovering from these failures in association with the logical state machines.

With reference to FIG. 4, the diagram depicts the states that a job transitions through during a data transfer process. It is contemplated the data transfer client component 204, the client-service interface in particular, may be configured to facilitate retrieving information about data transfer jobs. The information can include the current status of the job, the approximate percentage the each job has been completed, the current states of each drive, and URIs for data containing log objects with errors in accordance with embodiments of the present invention. Upon receiving an operation to generate a data transfer job, the data transfer job can be created and placed in the creating 402 state. While in the creating 402 state, the data transfer service can assume the drive has not been shipped to the storage service infrastructure. An import or export job may remain in the creating 402 state for up to a predefined period of time before it is automatically deleted by data transfer service. If an operation to update the properties of the job is received while the job is in the creating 402 state, the job will remain in the creating 402 state while resetting the timeout to a predefined time period.

The data transfer job can transition into the shipping 404 state based on an update to a state property using an update operation. The shipping 404 state may be set when package information (e.g., carrier and tracking number) have been set. The job can remain in the shipping 404 state for a predefined period of time, after the predefined period of time expires and the drive has not been received, the data transfer service and the storage service administrators can be informed.

Upon the drive arriving at the storage infrastructure and at least one drive having begun processing by the data transfer service, the job state can be changed to a transferring 406 state. Further, upon the drive having completed transferring data, the job can be placed in a packaging 408 state until the storage media are shipped back to the customer. It is contemplated that a job can be cancelled at certain states. A cancelled job will skip the data copy step, but otherwise it will follow the same state transitions as a job that was not cancelled

A data transfer job state may be changed to closed 410 to indicate that there is an exception, warning or error. For example, the drive completed with errors, or the number of drives was not sufficient for export. Customers can look for more details in the using the data transfer client component. Customers may also perform repair actions or create a new data transfer job, in accordance with embodiments of the present invention, to address any errors with the data transfer job. The data transfer job state complete 412 indicates that the job has finished normally. The data transfer job in the closed 410 or completed 412 state may be changed to a deleted 414 state. In particular, the data transfer job may be deleted after a predefined period of time or based on an explicit operation to delete the data transfer job.

During shipping 404 sate, the package for a job may not have arrived during a predefined time. The storage service administrators can notify the customer about the missing package. Based on feedback, the time to wait for the package to arrive may be extended or the data transfer job can be cancelled. In the event that the customer cannot be contacted or does not respond within a predefined period, the storage service administrators can initiate actions to move the job from the shipping 404 state directly to the closed 410 state.

During a closed 410 state or a completed 412 state, the drive may not have reached the return address or may have been damaged during shipment in an export job. If the drive does not reach the return address, the customer can first use the data transfer client component to check the job status to ensure the drive has been shipped. If the drive has been shipped, then the customer can contact the shipping provider to try and locate the drive. If the drive is damaged during shipment, the customer can request another export job or download missing data directly from the storage service infrastructure.

During a transferring 408 or packaging 408 state, if the data transfer job has an incorrect or missing return address, the storage service administrators can reach out to the contact person of the job to obtain the correct address. In the event that the customer cannot be reached, the storage media can be securely destroyed within a predefined period of time.

During a creating 402, shipping 404 state, or transferring 406 state if an additional drive that is not listed in the list of drives to be imported is in the shipping package, the extra drive may not be processed and can be shipped back when the job is completed.

During a data transfer job, several errors may occur. Errors may be associated with particular job states and triggered by events. The job state machine may define resolutions and or next steps for handling errors. By way of example, during a creating/undefined state one or more drives may arrive even though the job is not in the shipping state or there is no record of the job in the data transfer service. The storage service administrator can attempt to contact the customer as needed to create or update the job with necessary information to move the job forward. If the storage administrator is unable to contact the customer within a predefined period of time, the storage service administrator will attempt to return the drives. In the event that the drives cannot be returned and the customer cannot be reached, the drives will be securely destroyed in a predefined period of time. A job may not be processed until it enters the shipping state.

With reference to FIGS. 5A-B, the diagrams depict the states that a drive transitions through during a data transfer process. The storage service can support an operation to retrieve a current state of the drive. A drive state can be a specified 502 state for an import job, when the job is created using a data transfer service operation. For an export job, since no drive is specified when the job is created, the drive can start with a received 504 state. As such, an import job can transition to a received 504 state when the storage service administrator has processed the drive that id received from the shipping company. Again, specifically for an export job, the drive can start with the received 504 state. A drive state may be a never received 506 state when the package for a data transfer job arrives but the package does not contain the drives. A drive may also move into the never received 506 state when it has been over a predefined period of time since the shipping information of the drive was received but the package has not yet arrived at the storage service infrastructure.

A drive can also move to a transferring 508 state when the data transfer service first starts to transfer from the drive to the storage service infrastructure. The drive state may be moved to a completed state 510 when the data transfer service has successfully transferred all the data with no errors, and a complete more info 512 state when a drive has encountered some issues while copying data either from or to the drive. The info may refer to errors, warnings, or informational messages about overwriting data. The drive can be moved to a shipped back 514 state when it has been shipped from the storage service infrastructure back to the return address.

When a drive in an import job has been added using an operation at the client-service interface, the drive can be in the specified 502 state. When the drive appears at a storage service infrastructure as the result of a storage service administrator closing a ticket to receive goods, the data transfer management component transfers the drive to the waiting for transfer 516 state. When the drive cannot possibly arrive, due to no outstanding tracking numbers, the data transfer management component transfers the drive to the never received 506 state.

When a drive in a data transfer job is in the waiting for transfer 516 state, the drive can be sitting in a bin at the storage service infrastructure waiting to be loaded into a drive bay so that transfer may either begin or continue. When a drive enters the waiting for transfer 516 state, the drive may be assigned a timestamp. Based on this timestamp, and other rules governing insertion and removal of drives, the data transfer management component can write a ticket for a storage service administrator to insert the disk into a specific drive bay and transitions the drive to the load ticket filed 520 state.

The drive can be in the load ticket filed 520 state when a ticket has been filed to load the disk into a specific a drive bay, and an appropriate action has been perform to enable communication between the corresponding job, drive, ticket, and drive bay. If the ticket is overdue, or is failed, the drive can be moved to the faulted state 522 and an incident is raised. If the ticket is closed, the drive can be transferred into a load ticket resolved 524 state.

When the storage service administrator performs a loading task, the agent on the drive bay can detect the drive insertion and assign the drive to a VM, as described in embodiments of the present invention. The VM communicates with the data transfer management component to get information about the storage account used for the disk. Once the data transfer management component responds as to which job the drive insertion is for, and receives confirmation that the mount was successful, it changes the drive state to transfer 508 in progress. If the mount is unsuccessful, the data transfer management component files a ticket to remove the drive from the drive bay. When this is complete, the drive can be moved to a need unloading ticket 526 and upon the ticket being filed, to the unload ticket filed 528 state.

When a drive in a data transfer job is in the transferring 508 state, it has been loaded into a drive bay, a VM has been allocated, and files are being uploaded to the storage service infrastructure. The data transfer management component is responsible for making this state transition, based on the information the VM provides it. It is contemplated that the data transfer management component may further support restarting, resetting, or monitoring as needed for the VM as it transfers. If copy completes, or if it fails irretrievably, or on a timeout due to no progress, the data transfer management component can file a ticket to remove the drive from the drive bay. When this is complete, the drive is moved to the unload ticket filed 526 state.

When a drive in a data transfer job is in the unload ticket filed 526 state, it has successfully been loaded into a rack, and is now ready to be removed from that rack. A ticket is outstanding for a storage service administrator to perform that removal. If the ticket is overdue or failed, the data transfer management component moves the drive to the faulted 522 state and an incident is raised. If the ticket is closed, the drive still has data to transfer, and forward progress was made on this run, the data transfer management component can move the drive to the waiting for transfer 516 state. If the ticket is closed otherwise, the data transfer management component can move the disk to the waiting for ship 518 state, since the drive cannot make forward progress

When a drive in a data transfer job is in the waiting for ship 518 state, the drive is ready to be shipped back to the customer. When all drives from a bin are in the waiting for ship 518 state, the data transfer management component files a ticket to return the drives to the customer. This can be part of the package workflow.

When a drive in a data transfer job is in the shipped back 514 state, a storage service administrator has closed a ticket indicating that it has been successfully returned to the user, using a certain tracking number. The data transfer management component may take no action on the drive in this state. It is contemplated that interaction with the carrier could be incorporated to monitoring to help determine whether the customer has actually received the package. When all drives involved in the data transfer job are in the shipped back state 514, the job is in the completed state.

When a drive in a data transfer job is in the never received 506 state, either one of these two conditions can be true—all outstanding tracking numbers are over their timeouts and all tracking numbers have been received, but a drive listed in the import drive list has not been received within them. The data transfer management component can move a drive back to the specified 502 state if the user specifies a new tracking number using the client-service interface.

The data transfer service can also support several different fault states. When a data transfer job or storage medium fails to progress normally through its expected life cycle, the job or storage medium can be moved into a faulted state. At that point, the storage service administrator can contact the customer (e.g., by email or phone). Once the issue is resolved, the faulted job or drive can be taken out of the faulted state and moved into the appropriate state. When a drive in a data transfer job is in the faulted state, something has gone wrong and storage service administer may address any issues. The data transfer management component may take no action on the drive in this state. However, the storage service administrator can modify the state of the drive to allow all appropriate actions. In embodiments, a fault is implemented as a flag such that the job or drive stays in its current state but then marked as faulted. The fault flag may be a separate field associated with the job or drive. As such, the fault flag remains active and the job or drive is frozen in an associated state until the issue is resolved.

Data transfer service may further support cancelling, deleting, enumerating jobs. Each of these actions may be associated with an operation executable at the client-service interface. A customer may perform an operation via the client-service interface to configure the data transfer job during different logical states of the data transfer job. For example, a customer may request to cancel a data transfer job before the data transfer job is in a packaging state by executing a cancel operation. The cancellation can be done on a best effort basis, and if storage media are in the process of transferring data, more data may be transferred even after the cancel has been requested. A cancelled job may still run to the completed state and be kept for a predefined period of time, at which point it will be deleted. A customer may further execute a delete operation before the storage medium has been shipped (while the data transfer job is in the creating state). A data transfer job can also be deleted when the data transfer job is in the closed or complete state. After a data transfer job has been deleted, its information and status may not be accessible using the data transfer service. A customer can also enumerate the data transfer service jobs in a subscription by executing an enumeration operation. The operation can return the data transfer jobs including on the following attributes: type of job (Import or Export), current job state, job's associated storage account, and time the job was created.

With reference to FIG. 6, the diagram depicts the states that a drive bay transitions through during a data transfer process. The drive bay may be configured to receive a drive and facilitate importing or exporting the data on the drive. The drive bay may support several different logical states. The drive bay can be in an empty 602 state initially, as well as upon successful closure of an unloading ticket. If the management component selects the drive bay for transferring activity, the management component can file a ticket to load a drive into the bay and move the bay to the loading ticket filed 604 state. During the loading ticket filed 604 state there exists an outstanding ticket for a storage service administrator to load a drive into the drive bay. If the ticket is closed successfully, the data transfer management component moves the drive bay to the occupied 606 state. If the ticket is failed for some reason, the data transfer management component can move the drive bay to the faulted 608 state. The drive bay is in the occupied 606 state while there is a drive doing copying work inserted. When that drive is moved to the unload ticket filed 610 state by the data transfer management component, so is the drive bay.

During the unloading ticket filed 610 state a drive can be inserted in the drive bay, but a ticket is outstanding to remove the drive from this drive bay. If the ticket is closed successfully, the data transfer management component moves the drive bay to the empty 602 state. If the ticket is failed for some reason, the data transfer management component moves the drive bay to the faulted 608 state. The drive can be in a faulted 608 state when either a load or an unload ticket is failed for some reason. Human intervention can be needed to move the drive bay back to empty 602 state. The data transfer management component may take no action on the drive bay in this state. However, humans can modify the drive bay state to note that it has been repaired.

With reference to FIG. 7, package information (e.g., carrier and tracking number) can be provided by the customer through the client-service interface. For each tracking number associated with package information, the data transfer management component can file a ticket to receive the incoming package. Package entities go through various as listed in the FIG. 7. The package can be in the created 702 state when the package has been specified by an operation on client-service interface to update the data transfer job with the package information. The data transfer management component may take no action on tickets in this state. The package can be in the shipped 704 state when the customer sets the state of the data transfer job, the package can be associated with shipping. The data transfer management component can move the ticket to a shipped 704 state. As soon as the data transfer management component sees a ticket in this state, it can file a ticket to receive the tracking numbers at the appropriate storage service infrastructure, and move the state to receiving ticket filed 706. The package can be in the receiving ticket filed 706 state after the data management component sets the state of the tracking number to shipped and filed a ticket to receive the package at the storage service infrastructure. At this point, the tracking number can fundamentally be a ticket.

The data transfer management component can be responsible for monitoring the state of this ticket while the package is in the receiving ticket filed 706 state. If the storage service administrator closes the ticket, the ticket can have appropriate details about which drives were contained in the shipment. The data transfer management component can move the state on all the drives named in the ticket to the waiting for transfer state. Upon closure, if the associated data transfer job has a return address associated therewith, the data transfer management component can move the package to the waiting for ship 708 state. Otherwise, the data transfer management component can move the package to the waiting for return address 710 state. The package can be in the waiting for return address 710 state when it has been received at storage service infrastructure, but no return address is specified in the associated job. The data transfer management component can move the state of the package to waiting for ship 708 when the customer updates the return address. The data transfer management component may take no action on packages in this state. If the ticket is overdue, the data transfer management component can move the package to the overdue 712 state.

The package can be in the waiting for ship 708 state when the drive has been loaded into a bin at the storage service infrastructure. In addition, there is the necessary information needed to be able to return the drive to the customer. The data transfer management component is responsible for filing tickets for all drives in this bin to be loaded and unloaded from the bin. When all drives from this bin are in the waiting for ship 708 state, the data transfer management component can move the package to the shipping ticket filed 714 state upon successfully filing a ticket to ship the drives back.

The package can be the shipping ticket filed 714 state when the data transfer management component has filed a ticket to ship the drives in the bin back to the customer. If the ticket is overdue or failed, the package can be moved to the faulted 716 state. If a storage service administrator closes the ticket, the ticket will have appropriate details about the tracking numbers used to ship the drives back to the customer. The data transfer management component can move all the relevant drives to the shipped back state, then moves the package to the returned 718 state.

The package can be in the returned 718 state when the ticket to ship the drives is closed, giving the information about which packages were used to ship the drives to the customer. Note that the data transfer management component will create a new package entity for each tracking number listed in the ticket. Each of these entities will be in the outgoing package 718 state. The data transfer management component takes no action on tracking numbers in this state. The package is in the outgoing package 720 state when a storage service administrator mentions it when closing a return shipping ticket. The data transfer management component may take no action on tracking numbers in this state. The data transfer management component returns the tracking numbers of these tickets. The package can be overdue 712 or faulted 716 when a receiving ticket is open past its timeout or has failed in some way, respectively. The data transfer management component may take no action on tracking numbers in this state.

With reference to FIG. 8, the diagram depicts the states that a ticket transitions through during a data transfer process. When a drive is inserted or removed from a drive bay a loading ticket is created in a ticket filed 802 state. Upon ticket closure, the data transfer management component can move the loading ticket to either the successful close 804 state or the ticket failed 806 state, depending on the contents of the ticket reply. Upon ticket timeout, the data transfer management component moves the ticket to the ticket timed out 808 state.

A loading ticket can be in the ticket failed 806 state when the contents of the ticket upon closure are unexpected (bay does not exist, bay is inoperable, etc.). The data transfer management component may not modify the state of the loading ticket when in this state. However, human intervention can move the ticket from this state to some other. A loading ticket is in the successful close 804 state when the underlying ticket is closed and the contents upon closure are expected. The data transfer management component may not modify the state of this loading ticket further. A loading ticket can be in the ticket timed out 808 state when the underlying ticket has not been serviced in a timely fashion. The data transfer management component does, however, continue to monitor the state of the underlying ticket.
